Letters Patent No. 97,377

datedV November 3, 1869.

IMPRO'VEMENT' m eULTrvA'roRs.

The Schedule referred to in these Letter s Patent and making part of the name To all whom it may concern Figure 1 represents a side elevation of my invention;

Figure 2a rear elevation and Figure 3. a view of swivel-joint.

Tb'jenable others skilled in the art to make and use Ay represents the axle oi' cultivator, upon which turn the wheels B B.

a a represent the side beams beam of the cultivator.

, These, with the axle A and pole G, form a rigid frame, to which the various subordinate parts are at tached.

D D D D represent the shovelLbeams. p The beams D D are hinged, at their front ends, to the beam at.

rIl'he beams D D are also attached to the beam a', but they are connected by a swivel-joint, d, instead of a hinge.

The rear ends of the' beams D are connected by a rod, d, to the arms e of the rock-shaft E.

This shaft is operated, by means of the hand-lever I", in the usual manner.

` The beams D are not connected in -any way to the rock-shaft E, but are att-ached, instead, to the beams 1),by avloose joint, cl2.

Hl represents'a vertical standard, rising from the rear end of the pole, which is provided with a slot, h,

, and a', the front I represent-s a bow-shaped bar or rod, which is proridcd with a projecting pin,ii,rwhich passes through 'the slot 71. i

This piu is provided with a head, so that it is seh.' represents a spiral spring, located within the slot upon which rests the pin i ot' the bar I. p

J J represent rods, connecting the ends ot' the bar I wit-h thebealns D', as shown, these'rods being attached to the bea-ms at a point inside of their centre,

as shown.

. This connection is ynot arigid one, but is such as to permit `the beams to have proper play.

I( represents a rod, connecting the ends of the bar I, which is provided for the purpose of permitting the device to be operated-by the feet of the rider.

The construction of my shovels L is also peculiar. 'Ihey `are'shaped like a diamond, the lower half being the longest, however. p

By this form of tooth the ground can be stirred to a great depth, without injuring the plantsl` l The depth of the plows is regulated by means of the hand-lever F,

The operation of my machine is as follows:

When it is desired to swing the inside shovels away from the corn for any purpose, the bar I is depressed, and both of the inside shovels are, consequently, thrust out from the corn, this effect being produced by depressing the inner sidev of the beams, through the medium of the connecting-rods.

4This operation forces the beams to turn upon their joints, and the shovels are necessarily moved inan outward direction. r

By depressing either end of the rod, the shovels are moved simultaneously' to the side depressed.

By the simple construction and arrangement herein described, an operator can use the machine among crpoked corn, without fear of injury to the crop.

Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is

1. 'Ihe beams D', when provided with joints (l (Z2 at front and rear, as described, for the purpose set forth.

2. The standard H, bar I, and spring 7L', when constructed substantiallv described, for the purpose set forth.

3. The standard H, bar 1, and spring It', when combined with the ,beams D', substantially as and for thc purpose set fort-h.

4. The machine described', consisting oi' the frame A au a', wheels B B, pole C, beams D D', shovels L, rock-shaft E, hand-lever F, standard H, bar I, spring h', the whole being` combined and arranged as described.

This specification signed and witnessed, this 31st day 0f July, 1869.
